Let's drop a live grenade into a 1450-pound steel box, shall we?

Lauri and Anni Vuohensilta, the extremely Finnish hosts of YouTube’s popular, long-running Hydraulic Press Channel, generally seem to occupy the majority of their time by shoving various beloved cultural artifacts beneath the namesake industrial tool for the hell of it science. Their equally Finnish friend, Pommi Henkka, also runs the Beyond the Press channel, which as the name suggests, goes beyond their callous disregard for PSI to showcase a wholly different, more traditional hobby: shoving various objects into other objects, then seeing if they comically explode.
This week’s entry: dropping a live grenade into a 1450-pound, 2-inch-thick steel cube. Let’s learn the results, shall we? We mean, we know what’s gonna happen, but that doesn’t lessen the satisfaction of seeing something burst into flaming bits, now does it?
…Huh. Well, shit. That sucker is almost disappointingly durable, from the looks of things. Like, no cracks, no shrapnel, no nothin’. Sure, watching the hosts subsequently launch an anvil 40-feet in the air is pretty satisfying, but to be honest, we can’t help but feel a bit let down overall.
